The listIterator() method of java.util.AbstractList class is used to return a list-iterator containing the same elements as that of the AbstractList in proper and same sequence starting from a specific position or index number which is passed as a parameter to this method.
Syntax:
Java
Java
ListIterator new_list
= AbstractList.listIterator(int index);
Parameters: The parameter index is an integer type value that specifies the position of the element from where ListIterator starts operating and returning values.
Return Value: The method returns the list created using ListIterator, starting from the specified index.
Below program illustrate the AbstractList.listIterator() method:
Program 1:
// Java code to illustrate listIterator()
import java.util.*;
public class LinkedListDemo {
public static void main(String args[])
{
// Creating an empty AbstractList
AbstractList<String>
abs_list = new LinkedList<String>();
// Use add() method to add elements in the list
abs_list.add("Geeks");
abs_list.add("for");
abs_list.add("Geeks");
abs_list.add("10");
abs_list.add("20");
// Displaying the AbstractList
System.out.println("AbstractList:" + abs_list);
// Setting the ListIterator at a specified position
ListIterator list_Iter = abs_list.listIterator(2);
// Iterating through the created list from the position
System.out.println("The list is as follows:");
while (list_Iter.hasNext()) {
System.out.println(list_Iter.next());
}
}
}
Output:
Program 2:
AbstractList:[Geeks, for, Geeks, 10, 20] The list is as follows: Geeks 10 20
// Java code to illustrate listIterator()
import java.util.*;
public class LinkedListDemo {
public static void main(String args[])
{
// Creating an empty AbstractList
AbstractList<Integer>
abs_list = new LinkedList<Integer>();
// Use add() method to add elements in the list
abs_list.add(10);
abs_list.add(20);
abs_list.add(30);
abs_list.add(40);
abs_list.add(50);
// Displaying the AbstractList
System.out.println("AbstractList:" + abs_list);
// Setting the ListIterator at a specified position
ListIterator list_Iter = abs_list.listIterator(2);
// Iterating through the created list from the position
System.out.println("The list is as follows:");
while (list_Iter.hasNext()) {
System.out.println(list_Iter.next());
}
}
}
Output:
AbstractList:[10, 20, 30, 40, 50] The list is as follows: 30 40 50
